APPARATUS FOR ARRES'IING FUMES.

To all whom it may concern:

Be it known that I, ALFRED TOMKINS, a citizen of the UnitedStates of America, residing at Pittsburgh, in the county of Allegheny and State of Pei'insylvania, have invented certain new and useful Improvements in Apparatus for Arresting Fumes, of which the following is a specification, reference being had therein to the accompanying drawmg. 7

This invention relates to an apparatus for arresting fumes and has for its object to provide an apparatus that can be used in connection with metallurgical, reverbcratory and regenerative furnaces for collecting solid matter from the exhaust gases or fumes of said furnaces.

A further object of the invention is to provide an apparatus embodying cooled battles that are disposed in a manner as to provide a sinuous or circuitous passage, for gases or fumes, whereby the metallic particles contained within the gases or fumes will be deposited upon the batlles and collected at points that permit their ready removal.

Another object of the invention is to provide an apparatus for saving precious metals held in suspension by gases and fumes, and the invention further aims to accomplish the above results by a method and apparatus that will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein like numerals of reference denote corresponding parts throughout the several views, in which Figure 1 is a side elevation of an apparatus in accordance with this invention. Fig. 2 is a vertical longitudinal sectional view of the same taken on the line X-X Fig. 4. Fig. 3 is a horizontal sectional view of a portion of the apparatus taken on the line Y-Y Fig. 1, and Fig. i is an end view of the apparatus.

The reference numeral 1 denotes a portion of a metallurgical furnace, as a detinning furnace, said furnace having an exhaust flue or outlet 2. In communication with this fine or outlet is the apparatus which I employ for carrying my method into effect. The apparatus is preferably located upon a suitable foundation, as a concrete base 3 and comprises an outer frame work or structure made of structural steel and consisting of vertical I-bcams 4, longitudinal channel bars 5, transverse end channel bars 6 andlongitudinal and transverse tie rods 7. T his outer Specification of Letters Patent.

Patented Apr. 1,1913. Serial No. 659,630.

structure forms a frame for bracing the walls of the apparatus and said apparatus is made of a refractory or infusible material, as fire brick.

The structure contained within the outer frame work comprises longitudinal walls 8, end walls 9 and 10, transverse walls or partitions 11, baflie walls 12 and an arched or crenelated roof 13.

The end wall 9 has an opening 14: at. the bottom thereof. in communication with the fine or outlet 2, and the end wall 10 has the bottom thereof provided with an exhaust opening 15 that can communicate with a. stack, chimney or other structure (not shown).

The transverse walls or partitions 11 eX- tend theent-ire height of the apparatus, are equally spaced throughout the structure and approximately the upper half of each Wall is provided with a transverse air passage 16, extending from one side wall 8 to the other side wall 8. These air passages permit of air passing through the walls or partitions 11 for cooling the same. The lower half of each wall or partition 11 is provided with large ports or doorways 17 preferably two in number, as best shown in Fig. 4:, said ports being separated by a column 22.

The battle walls 12 are equally spaced between the transverse walls or partitions 11, said batlle wall extending from the bottom ofthe structure to a point in proximity to the roof of said structure and terminating at a point above the large ports or door ways 17. The walls have the upper end thereof beveled, as at 18 to provide deflectors, and said walls are provided with transverse air passages 19. The passages 19 extend from one of the walls 8 to the other and from the bottom of the structure to a point in close proximity to the top of said walls. The air passages 19 serve the same purpose as the passages 16,that of cooling.

The side walls 8 are provided at the bottom thereof with doorways 20 normally closed by hinged doors 21, these doorways permitting of easy access being had to the interior of the structure for removing dust or other matter.

Before setting forth the method involved in connection with my apparatus, I desire to make several structural reservations. First, that of using any cooling agent for the structure, particularly in connection with the walls 11 and 12. In

What I c 1. Au ap iiaratus 'ili Iructure to a. point 51 An apparatus for arresting fumes comprising a structure including side and end walls, a top and a bottom, transverse walls having their ends terminating in said side walls and extending from said bottom to said top, said transverse walls having air passages in their upper portions, said air passages opening through said top andsides into the atmosphere, said transverse walls further provided below said passages with ports, and battles positioned between said transverse walls, mounted upon said bottom and extending above said ports, said bafi'les extending from one side to the other side of said structure and having air passages opening through said side walls into the atmosphere, each of said end walls having an opening, and one .of said side walls provided with doorways.

6. An apparatus for arresting fumes-comprising a structure formed with spaced par. titioned Walls having air passages in the upper portions thereof said air passages opening into the atmosphere at the sides and top of said structure, the partitioned walls having ports in their lower portions and below said air passages, and battles-interposed between said partitioned walls of a height as to extend above said ports and having a-ir passages with their ends opening into the atnosphere at the sides of said structure.

In testimony whereof I aflix my signature in the presence of two witnesses.
